    agc loop design

    I need information about designing AGC(automatic gain control) circuit for VGAs (Variable Gain Amplifiers). How can I design an AGC circuit by using OP-Amps in the loop after detector? (Receiver, IF section)

    PRF protection

    Additional components and supplies are pain in the neck. Nobody wants his or her circuit be complex and expensive. What can be the easy way? Innovations are hidden in details!

    PRF protection

    Thanks elctricuwe and nbucska, I used a monostable multivibrator to protect the amplifier against duty cycle; there is no problem with duty cycle. Still struggeling to search a mcu which is appropriate for the design. Actually I have another debate for you guys: If you had two signals which...

    PRF protection

    Thanks guys, Your comments are very helpful. As I understood, I have to learn MCU programing. I have no idea about programing mcu but I think I can cope with. Have nice days

    PRF protection

    Thanks skogsgurra, I will use the circuit as the protection circuit of power amplifer transmitter bias. Since the amplifier is allready pushed in order to get more power than the power it is able to give in CW, when the higher PRF come to the bias, the transistor blows up. I don't have any...

    Calculating impedence of an flat rectangular bonding strap

    The best and reliable way to find the empedance of any three dimensional object is to simulate them in 3D simulators like HFSS, CST and KCC (depending on frequency of course.

    PRF protection

    Hello, I have a pulse repetetion frequency protection circuit (PRFPC)project. Actually I designed a five order active filter (by using two LM741) for this work. My purpose is to attenuate the input voltage of the PRFPC with the multiplied of 0.25 (If Vin=4V=> Vout=1V) at 4kHz, which is a...

    CST Microwave Studio

    Hi, I am trying to learn CST Microwave Studio, but I have difficulties to define ports and boundry conditions in CST. Could you please send me detailed information about defining boundries. Thanks Erdogan Alkan ealkan78@hotmail.com
